If ferries are part of my Istanbul plan this week, I am checking the timetable again. Şehir Hatları, the city’s municipal ferry operator, switched from its summer schedule to the 2026–27 winter timetable on Monday 7 September. The new timetable runs until 27 June 2027.
This is not a shutdown or a dramatic reduction in service. Şehir Hatları says the winter network continues across 32 lines with an average of 826 sailings a day. The practical problem is simpler: a saved summer timetable, an old screenshot or a blog post with one favourite departure time may now be wrong.
What actually changed on 7 September?
The seasonal timetable changed. Şehir Hatları’ summer schedule ended on 6 September, and the winter schedule began the next day. That means the network is still extensive, but individual departure times, stopping patterns and route frequencies can differ from the summer period.
I would not try to memorise the whole change. I would treat the date as a reset point: any ferry plan created before 7 September gets checked again against the official timetable.
But averages do not tell me whether my 17:40 crossing still leaves at 17:40. A relatively small network-level change can still move the exact boat I care about, which is why I check the route rather than relying on the headline number.
At network level, the summer announcement described an average of 839 sailings a day; the winter announcement gives an average of 826. That is a useful reminder not to exaggerate the change into “ferries stop in winter”. The system is still running hundreds of services every day.
How big is the seasonal change?
The ferries are still everyday public transport
It is easy to talk about Istanbul ferries as if they are scenic attractions. They are scenic, but they are also normal city transport. Crossings between the European and Asian sides can be a practical way to move between neighbourhoods such as Kadıköy, Üsküdar, Karaköy, Beşiktaş and Eminönü, while longer services and island routes shape whole day trips.
That is why a seasonal timetable change matters to travellers. A ferry is not just the pretty part between two itinerary pins; it may be the actual connection that makes the day work.
Princes’ Islands: check the return before you leave
The winter announcement is good news for visitors planning Büyükada or Heybeliada: Şehir Hatları says night sailings on the Bostancı–Adalar ring continue every day through the winter period.
I still would not build an island day around the final possible boat. I choose a comfortable return before leaving the mainland, then treat later services as flexibility rather than permission to stop watching the time. Weather, crowds and operational changes can all matter on the day.
Our day-trips guide now uses the new winter schedule as its planning baseline for the Princes’ Islands.
Weekend night ferries still connect Kadıköy, Karaköy and Beşiktaş
The winter timetable keeps overnight services on the Kadıköy–Karaköy–Beşiktaş line on the nights linking Friday to Saturday and Saturday to Sunday.
For visitors, that is useful because these are exactly the areas where a late dinner, bar stop or evening walk can push past an ordinary daytime plan. I still check the exact late-night departure and pier before going out; “night service exists” is not the same as “a boat leaves whenever I feel like turning up”.
The official Long and Short Bosphorus Tours continue daily
Şehir Hatları also confirms that both its Long Bosphorus Tour and Short Bosphorus Tour continue to operate every day during the winter timetable period.
This matters because a normal commuter ferry and an official sightseeing tour solve different problems. If I simply want to cross the Bosphorus, I use a scheduled city service. If I want a deliberate water-based sightseeing block, I compare the current Long and Short Tour timetable and choose around the rest of the day.
Our Bosphorus cruise guide explains that distinction in more detail.
Sea Taxis remain a 24/7 option
Şehir Hatları says Istanbul’s Sea Taxi service continues 24 hours a day, seven days a week. I see that as a separate transport product, not a substitute for pretending the scheduled ferry timetable does not matter.
For most ordinary sightseeing days, public ferry services are the simple first option. A Sea Taxi can be useful for a specific journey, timing problem or group, but I would check the live booking conditions and price before treating it as the backup plan.
Do not confuse Şehir Hatları with every boat on the Bosphorus
Istanbul has municipal ferries, private ferry operators, excursion boats, dinner cruises and private yachts. The 7 September winter timetable announcement is specifically about Şehir Hatları.
If my ticket or route belongs to another operator, I check that operator’s own current schedule. “Istanbul ferry timetable” is not one universal document covering every vessel on the water.
What I would re-check before a normal central crossing
- Exact route: which line actually serves the two piers I want.
- Exact pier: large waterfront districts can have several adjacent terminals.
- Departure on my date: weekday, weekend and seasonal patterns can differ.
- Return option: especially when the ferry is part of an evening plan.
- Live weather or service notice: marine transport is more weather-sensitive than a tram ride.
The city is much easier when I check those five things once instead of discovering at the waterfront that the timetable in my phone belongs to August.
What about fares?
I am deliberately not turning this news post into a static fare table. Şehir Hatları prices vary by route and can change independently of the seasonal timetable. Some longer routes and designated night services are treated differently from a short central crossing.
For current prices I use the operator’s live tariff information and the pier signage. Our Istanbul ferries guide explains the Istanbulkart and route-planning basics without pretending every boat costs the same.
A better way to plan a ferry day
- Start with the destination, not a saved departure time. Decide whether I am crossing town, touring the Bosphorus or spending a day on the islands.
- Open the live timetable for the travel date. The winter schedule is now the baseline.
- Check the return before boarding. This matters most for islands and late evenings.
- Leave some margin. Ferries are reliable public transport, but weather and busy terminals are real.
- Re-check on the day. A current operator notice beats this article the moment anything changes.
Bottom line
Istanbul’s ferries did not disappear when summer ended; the timetable changed. The winter network still gives visitors an enormous amount of freedom: 32 lines, hundreds of daily sailings, daily night services to the Princes’ Islands, weekend overnight connections between major nightlife districts and daily official Bosphorus tours.
The traveller mistake is not “using ferries in winter”. It is using an old summer timetable after 7 September. I would keep the ferry plans — and refresh the departure times.
Cheers, Carpe Diem & Catch the Right Ferry! 🍻⏳⛴️
